Re: benign beekeeping?

Dead mites on the bottom board of a failing hive disappear pretty quickly. Scavengers of all sorts collect them. In our part of the country ants and yellow jackets make short work of them.

This doesn't appear to happen in my neck of the woods. If I didn't dump and kill the live ones in my trays I wouldn't have a good indication of whether the fall is increasing or decreasing. Also, there are no ants or wasps in the dead of winter when the hive dies. I will give Solomon the benefit of doubt that he can tell if mites did his hive in. I could be wrong.

fair enough. some have been offered already.

but let's suppose these hives happened to have some resistance to varroa, and were never really challenged in their original location. then they were moved, and ended up robbing out other hives collapsing with varroa. in the process of robbing, they picked up a lot of mites, brought them home, and were challenged with a load that even their resistance could not handle.

if you didn't do mite counts, what other method(s) were used to determine the absence of mites?

journaling the growth of a treatment free apiary started in 2010. 20+/- hives

Re: benign beekeeping?

Also, there are no ants or wasps in the dead of winter when the hive dies.

As of today, here I see plenty of both.

Keep in mind, I never said that mites did his hives in. I do strongly believe that mites are part of nearly any collapse and small, sickly winter clusters are typical symptoms.
At least Ace, it appears that you know you have mites in your hives. And if those hives fail, I hope you will accept that mites contributed to their demise.

I look at brood patterns. When I see any significant spotting and/or workers uncapping brood it is usually a sign of mite. Then you test for them if you are so inclined. I did not test this fall. When I pulled honey and extracted I noticed spotty patterns. Then when uncapping the honey I had a few drone cells in the comb(I don't use excluders, except during the tupelo bloom) I saw mites on the drone brood I pulled. So I treated with apiguard.

Ace,

You never really want a spotty brood pattern. But yes, it is a sign of hygienic behavior and pretty much all my hives exhibit it. But I still treat if the mite levels look to be too severely depleting the overall hive populations. In my area a weakened hive will succumb to SHB.

I have only purchased 4 queens (six if you include the two that came with my original purchase hives) in three years. The balance are from my selected best performers and the cutouts and swarms I collect( mostly cutouts).

So what do you guys think. A should I just let a hygenic hive that is weakened succumb or treat. You know my answer so answer this for yourself not me

Re: benign beekeeping?

Yes I know what your referring to Brian. Like I said long cold spells can prevent the hive from accessing honey. Especially if there is brood present late winter. But I will also tell you that I have not had a single strong wintering colony starve like this. Only the smaller ones. We will sometimes get cold snaps that hover in the -30 degrees C for weeks on end, 5 year ago or so we had a three week streak that our daily highs did not rise above -32 degrees C. That year I was wintering outdoors still and most all of my small hives died, but the larger hives chugged along!
Most winters there are mild breaks that allow the hives to reorganize

I would also say that it is late in the winter, maybe early spring where brood is being raised so they can't leave yet their need for food is greater. These conditions will not happen in the south because there are not extended periods of cold weather. Is it a beekeeper mistake? Probably, but what can you do or not do to prevent it?

Re: benign beekeeping?

OK, so what do you, Michael and Ian, consider a strong colony? And, when do you decide that?

Is 8-10 frames of bees late summer/early fall strong? Do you like to see stronger?

Tom

Tom: If you have a full box of bees in a fairly tight cluster I would say you have a pretty strong hive anything more than that would be a bonus. I would think if they have ample stores and reasonable protection from the elements that they would be a lock to make it through an Ohio winter. I am assuming varroa levels to be fairly low to have come into winter with a cluster that size.

Re: benign beekeeping?

Whats your thoughts on that?

Its not whether your hives are 10 plus frames or not, thats not the point. Its whether or not you hives have meet your targets strengths.
Ill give you some examples

I winter in Canada, COLD. Now when I was wintering outside, my target population was 10 frames of bees plus. Anything entering at 10 frames I would consider a sure bet to survive. Now I winter indoors, my target population is 5 frames of bees plus, anything entering at that or above I would consider high chances to make it through. I also winter nucs, I want 3 frames with them.
I would never be able to winter a nuc entering winter with three frames outdoors here,

The point is, if the hive is managed to be a certain target strength according to your area's "climatic rules" and the hive misses the target, then something went wrong along the way. That hive entering winter smaller than was expected has a higher chance to die, cold and hungry.

I would say that if you had a double deep hive w/ a colony when the two boxes are tipped forward you could see the bees hanging below the bottomk bars of the bottom deep and then when you removed the cover(s) you coulkd see bees between the frames in the upper deep, that would be a strong colony, in Oct. or Nov.

Re: benign beekeeping?

>>look at the feral colonies, they are getting by just fine without any intervention......

and related to the point of the topic,
those ferals had to meet certain targeted strengths and targeted disease control on their own accord. If they didnt measure up in anyway, the good old arm of mother nature would kill them off. Those hives would starve inches away from honey also, but it wasnt starvation that killed them. Thats the only point I was trying to make

Re: benign beekeeping?

Sorry to leave you hanging there boys. I went to see a movie.

I don't have any solid proof that those hives didn't die of mites or problems related to mites. That wasn't the point. Nor did I ever say if anyone had been paying attention that I have no mites. The point was that where they were they were fine and when they were moved they died. The isolation argument is irrelevant because they are more isolated here not less. The small cluster argument is irrelevant because they weren't small clusters. But they did die and as far as my methods go, the only response is move on with the living.

Show me the studys. Show me the data. Show me the books. I think there are a lot of assumptions about feral colonies amongst beekeepers. I think it is safe to say that feral colonys exist w/out beekeeper intervention, but to say they exist, or survive, "just fine" w/out intervention may be a stretch. Unless you consider how long a colony continually occupys a cavity in a live state.
